10種のMOF系多孔性液体によるSO2回収を比較し、CALF-20/NHDが最適であることを見出した。0.1barで0.12mol/Lの吸着能、SO2/N2選択性562、SO2/CO2選択性51を示し、吸着エンタルピーは30.44kJ/molと低い。複数回の破過試験でも性能が維持され、99.95%純度で捕捉仕事は0.946GJ/t SO2、炭素鋼への腐食性も低く工業的脱硫への応用可能性を示す。
English
A comparative study of ten MOF-based porous liquids for SO2 capture identifies CALF-20/NHD as optimal, with 0.12 mol/L uptake at 0.1 bar, SO2/N2 and SO2/CO2 selectivities of 562 and 51, and low uptake enthalpy (30.44 kJ/mol). Performance is stable across breakthrough cycles, capture work reaches 0.946 GJ/t SO2 at ≥99.95% purity, and the saturated liquid shows low corrosivity to carbon steel over 60 days, indicating industrial desulfurization potential.

📝 gxceed 編集解説 — Why this matters
日本のGX文脈において
SO2は主に大気汚染規制の対象で、日本のGX・気候開示の文脈とは直接の接点は薄い。ただし排ガス処理の省エネルギー化・低腐食材料はプラントの運転コスト低減に資する。
In the global GX context
SO2 capture sits largely outside the TCFD/ISSB climate-disclosure agenda, but low-energy, low-corrosion desulfurization materials can support industrial decarbonization and air-quality compliance in heavy industry.

📄 Abstract（原文）
Currently, efforts are being made to develop desulfurization technologies featuring high desulfurization efficiency, renewable desulfurizers, and low corrosivity. In this study, a comparative study was conducted of SO2 capture by ten kinds of metal–organic framework (MOF)-based porous liquids. Calgary framework-20 (CALF-20)/poly(ethylene glycol) dimethyl ether (NHD) with pore width of 5.2 Å × 5.7 Å are found to be optimal for SO2 capture, exhibiting an a(b)dsorption capacity of 0.12 mol/L under 0.1 bar. The selectivity of SO2/N2 and SO2/CO2 achieves 562 and 51, respectively, and the uptake enthalpy for SO2 is only 30.44 kJ·mol–1. Furthermore, after multiple breakthrough experiments, the uptake still remained unchanged. Meanwhile, process simulations were conducted; when SO2 mol % (≥99.95%) is in the product gas, the capture work is only 0.946 GJ/t SO2. Additionally, the saturated CALF-20-based porous liquids exhibited low corrosivity to carbon steels even after being immersed for 60 days; this anticorrosive absorbent reveals the potential for industrial SO2 capture.
